**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 5.4.89 **Description** A kernel panic issue has been resolved in the Linux kernel. The problem occurred during the unload and load of ath11k modules, causing a kernel panic due to an internal error. The issue was related to the `napi by id` function and the `netif napi add` function. The error was triggered when the `ath11k ahb config irq` function was called, leading to a crash. The issue was identified on a Generic DT based system with a CPU PID of 4435. **Recommendations** For Linux kernel version 5.4.89 and earlier, update to a newer version to resolve the issue. As a temporary workaround, consider disabling the `ath11k ahb config irq` function until a patch is available. Restrict access to the `ath11k ahb` module to minimize the risk of exploitation. Avoid using the `napi by id` function in the affected API endpoint until the issue is resolved.
